Unequal Coherent Ergotropy at Equal Interferometric Visibility and Energy in Quantum-Controlled Interferometers
Tonipe Anuradha, André H. A. Malavazi, Borhan Ahmadi +2
The ergotropy, or unitarily extractable work, of a quantum system naturally splits into incoherent and coherent contributions, respectively set by population inversion and coherenc…
Communication-constrained nonlocal correlations
Lucas Pollyceno, Denis Freudenheim, José Nogueira +3
Identifying the physical grounds distinguishing quantum theory from broader probabilistic frameworks remains an open challenge. Communication-based proposals -- most notably the pr…
Certifying semi-device-independent security via wave-particle duality experiments
Chithra Raj, Tushita Prasad, Anubhav Chaturvedi +8
Wave-particle duality is known to be equivalent to an entropic uncertainty relation based on the min- and max-entropies, which have a clear operational meaning in quantum cryptogra…
Security of device-independent quantum key distribution via monogamy relations from multipartite information causality
Lucas Pollyceno, Anubhav Chaturvedi, Chithra Raj +2
Beyond the foundational significance, the problem of bounding nonlocal correlations by reasonable physical principles has meaningful practical consequences, particularly for device…
Wave-particle duality using the Compton effect
Lucas S. Pollyceno, A. D. Ribeiro
Thought experiments based on the double-slit interferometer had a crucial role to develop ideas concerning the wave-particle duality and the Bohr's complementarity principle. Ideal…
